Dice box are slim that you’ll ever play in a casino game with crooked dice at today’s casino. However, once in a while, some idiot tries to cheat the machine by inserting crooked dice into the game. By sticking with strict policies for controlling the overall game, casinos eventually catch even the most skilled slight-of-hand artists.
Each player must handle the dice with only 1 hand and must not bring the dice beyond your table. Both of these simple rules make the cheat’s job extremely tough. To make it more difficult, the table has a mirror along the entire length of the wall opposite the boxman therefore the boxman is able to see if the shooter is “palming” dice. Additionally, each time a die leaves the table following a roll, the die doesn’t keep coming back into play until after the boxman thoroughly inspects it. The dice are replaced at random times during the day and typically don’t stay in play for more than 24 hours.
Crooked dice come in many forms, such as loaded, painted, capped, tripped, bricks, and floaters. Loaded dice are heavier using one side. Painted dice have a solution applied to one side to create it stickier. Capped dice are shaved on one or more sides and the removed material is replaced by way of a material with different bounce characteristics. Tripped dice have their edges altered so they’re not all equal. Bricks (a.k.a. flats) have one side shaved to lessen the surface area of the adjoining sides. Floaters (because they float in water) have an off-center hole included. Shapes are dice that aren’t perfect cubes (some or all sides are either concave or convex).
The intent of crooked dice, regardless of their form, is to alter the likelihood of certain numbers appearing. A good slight change in the chances of a certain number appearing may be enough to change a small house advantage into a small player advantage. “Passers” are crooked dice modified to favor point numbers, while “missouts” are modified to favor the quantity 7.
